Electronic certificates

Electronic certificates may be used for travel on United- and United Express®-operated flights, and United Express-marketed flights operated by other airlines. Certificates are not valid for travel on Star Alliance™ flights or United-marketed flights operated by other airlines. If you have an electronic certificate or a discount code for a travel certificate, please select one of the options below for instructions.

Just above the “Search” button, select the option to search by schedule or by price. You will not be able to use your certificate if you search by award travel.
